What Is a Scientific Calculator?
Mode:
A Scientific Calculator is a type of calculator designed to solve advanced mathematics, trigonometry, algebra, logarithmic, and exponential functions. Unlike basic calculators, scientific calculators include support for constants like π (pi), square roots (√), factorials (!), and trigonometric functions like sin, cos, tan, and their inverses.
Whether you’re a student, teacher, engineer, or math enthusiast, a scientific calculator is a must-have tool for solving complex calculations efficiently.
